Movie I saw on Delta Flight

I saw a movie while on a delta flight. I don’t remember the title and never got to finish it.

I think it was Chinese, but don’t weigh that too much(I don’t remember and not 100% sure)

It starts out with this kid with a glowing blue hand getting bullied and he runs off and hides. He finds a creature that kind of looks like a pangolin/armadillo, and he befriends it. Then it cuts to where he’s older and he’s like an expert theif.
